This article focuses on "how to use the java delegation event model". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let the editor take you to learn how to use the java delegated event model.

1. A specific event is initiated by the event source and sent to one or more event monitors.

2. The monitor waits during this process until it receives the event, then processes the event and returns.

The implementation code registers (or removes) the listener as the receiver of a specific event type and triggers the event at the appropriate time.

Example

Import java.awt.*; import java.awt.event.*; public class MyFrame implements ActionListener {/ / implement ActionListener listener interface Frame f; Button bt; public MyFrame () {f=new Frame ("MyFrame"); / / instantiate window f.setSize (400,300); / / set window size f.setLocationRelativeTo (null); / / set window center display bt=new Button ("OK"); / / instantiate Button button bt.addActionListener (this) / / register listener object f.add (bt); / / add button bt to window f f.setVisible (true); / / set window to display} public static void main (String [] args) {/ / TODO Auto-generated method stub new MyFrame ();} @ Override / / implement listener interface method public void actionPerformed (ActionEvent e) {/ / TODO Auto-generated method stub System.exit (0) / / end the program}} at this point, I believe you have a deeper understanding of "how to use the java delegation event model".
